What can be done if a mare has a normal cycle, ovulates - is bred on that cycle and then 8 or so days later has a 2ndary cycle with a dominant follicle? This happened to a mare last year with my vet - after going through a lot of semen, I gave up. I am breeding myself this year with u/s and wanting to find a solution to manage this. Would putting the mare on regumate be an option at say day 5 after the 1st cycle. Is the fact that the mare is developing another 2ndary wave of follicles indicative that the mare did not catch from the first breeding?
Mares can, will, and do develop secondary follicular waves. It is perfectly normal, and has no negative impact on establishment or maintenance of pregnancy. There is no need to contemplate the use of Regumate (which will not suppress follicular development anyway). The presence of a second follicular wave is indicative of nothing - other than the fact that she is a normal mare in that regard!
If she is not getting or staying pregnant, it's because of something else.
